Every developer wants to be more productive. But between the endless stream of "productivity hacks" and the reality of daily coding, it's hard to know what actually works. These 10 tips are battle-tested strategies that have measurably improved developer efficiency.
💡 The Productivity Paradox: The most productive developers aren't the ones who type fastest—they're the ones who think before coding, automate repetitive tasks, and protect their focus time.
1 エディターのキーボード ショートカットをマスターする
The mouse is a productivity killer. Every time you move your hand from keyboard to mouse, you lose momentum. Learn these essential shortcuts (VS Code examples):

2 2 分ルールを使用する
If a task takes less than two minutes, do it immediately. This applies to:
- Responding to a quick Slack question
- Fixing a typo you just noticed
- Adding a TODO comment
- Approving a simple PR
The mental overhead of tracking small tasks often exceeds the time to complete them.
3 デバッグをタイムボックス化する
Set a timer for 25 minutes. If you haven't solved the bug by then:
- Take a 5-minute break (walk away physically)
- Explain the problem to a rubber duck (or colleague)
- Post on Stack Overflow or ask for help
This prevents the "I've been stuck on this for 4 hours" syndrome. Fresh eyes—yours or someone else's—often spot the issue immediately.
4 コードを書きながらコードのコメントを書く
Don't wait until you're "done" to add comments. Write them as you go:
- Start with a comment describing what the function should do
- Comment tricky logic while it's fresh in your mind
- Mark assumptions and edge cases
Comments written later are often incomplete because you've forgotten the nuances.
5 長時間労働を守る
Context switching is devastating for coding. Studies show it takes 23 minutes to regain focus after an interruption.
- Block 2-4 hour chunks on your calendar for coding
- Turn off Slack/Teams notifications during focus time
- Use "Do Not Disturb" mode
- Batch meetings together instead of scattering them
Pro tip: Early morning or late afternoon often has fewer interruptions.
6 反復的なタスクを自動化する
If you do something more than twice, automate it:
- Create shell scripts for common commands
- Set up code snippets for boilerplate
- Use pre-commit hooks for formatting and linting
- Configure CI/CD for testing and deployment
git config --global alias.co checkout
git config --global alias.br branch
git config --global alias.st status
7 ジョブに適切なツールを使用する
Don't fight your tools. If something is frustrating, there's probably a better way:
- Terminal multiplexer (tmux) for managing sessions
- Proper diff/merge tools for conflicts
- Database GUIs for complex queries
- API clients (Postman, Insomnia) for testing endpoints
Time invested in learning tools pays dividends forever.
8 コードを書く前にコードを読む
Before implementing a feature, spend time understanding the codebase:
- How do similar features work?
- What patterns does the team use?
- Are there utility functions you can reuse?
This prevents reinventing the wheel and ensures consistency. A 30-minute reading session often saves hours of refactoring later.
9 計画を立てて一日を終える
Before logging off, write down:
- What you accomplished today
- The first task for tomorrow morning
- Any blockers or questions you need answers to
This "shutdown ritual" lets your brain stop processing work, and you'll hit the ground running the next day.
10 本格的な休憩を取る
Sitting at your desk scrolling Twitter is not a break. Real breaks:
- Walk outside for 10 minutes
- Do a quick stretch routine
- Grab water or coffee (hydration matters)
- Chat with someone about non-work topics
Your brain needs downtime to process and consolidate information. Many "aha!" moments happen during breaks.
ボーナス: 時間を追跡する
For one week, track how you actually spend your time. Many developers are shocked to discover how much time goes to meetings, Slack, and context switching versus actual coding. Data reveals opportunities for improvement.
結論
Productivity isn't about working more hours—it's about maximizing the output of the hours you work. Start with one or two tips from this list. Once they become habits, add more.
The compound effect of small improvements is remarkable. A 10% productivity gain each quarter means you're nearly twice as productive in just two years.
